Short-Shank Fixed-Knuckle Coupler pkg(8)

Fixed-Knuckle Couplers from Fox Valley Models feature a T shank that's a drop-in fit for older Rapido-style couplers and other models with a "T" shank. While not automatic uncoupling or coupling, they can be used to manually couple to most knuckle couplers. Available in short, medium and long shank lengths. Molded in black plastic.
